Description
Technical field
The present invention relates to netting gear field, more particularly to a kind of air-purifying net and preparation method thereof.
Background technology
In recent years, with industrialized development, air pollution is increasingly severe, had influence on daily life and
It is healthy.The survey showed that, occurs the number of days of haze weather in some big cities of China and has 100～200 days in 1 year.
So-called haze weather, refer to nitrogen oxides in air, particulate matter total amount it is big, cause low visibility.Air during haze weather
In main component have the particles such as dust, sulfuric acid, nitric acid, organic hydrocarbon compounds, these harmful particles can be directly entered simultaneously
Stick on human body in lower respiratory tract and the lobe of the lung, during upper and lower respiratory tract and alveolar can be deposited on, cause rhinitis, bronchus
The illnesss such as inflammation, being chronically at this environment can also induce lung cancer.
The time of people daily an average of about more than 80% is spent indoors, the pass of IAQ and health
